Giant Arachnoid Granulation Associated With Anomalous Draining Vein: A Case Report., Randle Umeh, Rod J Oskouian, Marios Loukas, R Shane Tubbs

Articles, Abstracts, and Reports

Giant arachnoid granulations (AG) can mimic intracranial lesions. Knowledge of these structures can help avoid misdiagnosis when interpreting imaging. Here, we report a child who presented with a mass within the superior sagittal sinus and an anomalous draining vein. Herein, the diagnosis of a giant AG was made. Clinicians who view or interpret imaging of the head should be aware of these anatomical variants and though when very large, apparently, do not necessarily result in pathology. Based on our case report, giant AG might also demonstrate anomalous draining veins.
